Senior Geologist

Job Summary

• To provide advanced geophysical and geological expertise for reservoir characterization, seismic interpretation, static modelling, volumetrics and well planning to support field development, reserves maturation, drilling operations, and reservoir management.
• The role ensures high-quality subsurface evaluations, integrates multidisciplinary datasets, and drives optimal decision-making for hydrocarbon asset value maximization.

Key Responsibility Areas (Kras) & Initiatives
Reservoir Characterization & Static Modelling:

• Lead the development, integration, and updating of 3D static reservoir models (structural, facies, and petrophysical modelling).
• Integrate seismic, geological, petrophysical, core, and reservoir engineering datasets to deliver accurate reservoir descriptions and uncertainty analyses.
• Generate reservoir quality maps, volumetrics, and scenario-based models to support infill drilling, field development planning, and reserves estimation. ▪ Ensure modelling workflows follow subsurface assurance guidelines, data quality standards, and corporate modelling protocols.
• Support reservoir surveillance initiatives by integrating production and pressure data into dynamic/static model updates.

Seismic Interpretation & Geophysical Evaluation:

• Conduct advanced 3D seismic interpretation for structural definition, reservoir delineation, stratigraphic analysis, and prospect identification.
• Apply modern geophysical tools including AVO/AVA, seismic inversion, spectral decomposition, rock physics, and attribute analysis for reservoir prediction and fluid characterization.
• Provide QC oversight for seismic acquisition and processing projects to ensure optimal data quality.
• Develop and maintain seismic databases, interpretation projects, and geophysical technical documentation.
• Generate subsurface maps (structure maps, isopach maps, facies distribution maps), to support reservoir delineation and well placement decisions.

Well Planning, Drilling Support & Operational Geoscience:

• Lead subsurface input into well planning processes including well trajectory design, target definition, hazard assessment, and drilling risk mitigation.
• Provide real-time geoscience support during drilling operations (geosteering, stratigraphic correlation, LWD/MWD interpretation).
• Prepare end-of-well reports, geological prognosis documents, and post-drill evaluations.
• Collaborate closely with drilling, reservoir engineering, and production teams to ensure safe and optimized execution of drilling campaigns.
• Evaluate and recommend opportunities for sidetracks, re-entries, and well interventions.

Field Development, Reserves & Regulatory/Partner Support:

• Contribute to Field Development Plans (FDPs), Reservoir Management Plans (RMPs), and annual reserves reviews.
• Prepare subsurface technical documentation for regulatory submissions, JV partner reviews, and internal approvals.
• Support reserves reporting (1P/2P/3P) through rigorous subsurface analysis and documentation aligned with SPE-PRMS standards.
• Participate in technical workshops, peer assists, partner technical meetings, and regulatory engagements.
• Track, update, and maintain technical deliverables required for well approvals, development decisions, and subsurface assurance.

Research, Innovation & Continuous Improvement:

• Identify and implement new technologies, workflows, and software tools (AI/ML subsurface analytics, advanced inversion, 4D seismic).
• Document lessons learned, update best practices, and contribute to knowledge-sharing initiatives within the department.
• Mentor junior geoscientists, providing technical guidance and reviewing work to maintain high-quality subsurface deliverables.
• Ensure data integrity, digital compliance, and adherence to corporate subsurface governance standards.
• Support improvements in modelling workflows, seismic interpretation practices, and multidisciplinary collaboration.

Qualifications & Experience Requirements

• BSc or MSc in Geophysics, Geology, Earth Sciences, or related subsurface discipline.
• 8–12 years of experience in geophysics/geology roles within oil & gas E&P environments.

Required Professional Certifications / Accreditations:

• Membership in recognized professional bodies (NAPE, AAPG, SEG, EAGE, NMGS).
• Advanced training in seismic interpretation, reservoir modelling, or rock physics (advantageous).

Required Technical Experience Proven ability in:

• 2D/3D seismic interpretation and mapping
• 3D static reservoir modelling (structure, facies, petrophysics)
• Prospect generation and risk assessment
• Well planning, drilling operations support, and geosteering. Integration of core, logs, seismic, and production data
• Use of major subsurface software (Petrel, Kingdom, Hampson-Russell, Tnavigator, Decisionspace)
• Reservoir surveillance interpretation and volumetric estimation.

Additional (Desirable) Experience:

• Experience with 4D seismic, advanced inversion, AI/ML geoscience tools
• Exposure to carbonate/clastic reservoirs and deepwater environments
• Knowledge of reserves reporting standards (SPE-PRMS)
• Familiarity with petroleum system modelling or geomechanics
• Expert in interpretation of structural/stratigraphic features, seismic attributes, and fault/fracture systems.
• Builds and updates 3D geological models incorporating facies, petrophysical properties, and uncertainties.
• Applies inversion, AVO/AVA, and rock physics techniques to enhance reservoir prediction.
• Combines geological, geophysical, petrophysical, and production data into coherent subsurface models.
• Designs well trajectories, identifies hazards, and supports geosteering and realtime drilling decisions.
• Contributes to surveillance reviews, reserves maturation, and optimization of field development strategies.
• Ensures integrity, quality control, and lifecycle management of seismic, well, and modelling data.
